Hello,
I'd like to read in a few enviroment variables for an application that will automate a few tasks. VB has a function 'Environ' that can look up env variables with the key as the parameter. Is there anything simular in C#? It it's not possible through C# then I assume to use some api calls.
Thanks,
Bic2k

Yup, figured it out myself of course.
string path = System.Environment.GetEnvironmentVariable("PATH");

Please note that the environment variables created within the application will not be
available after the application exits.

Hi all,
In C# system service I need to get some string from MFC mainframe
window by SendMessage() API call. I managed to send message, but can
not find the way to return string to C# app.
I tried to use lParam:
C# side
StringBuilder sb = new StringBuilder(256);
SendMessage(process.MainWindowHandle, WM_GET_AUTH_MEMBER, 0, sb);
C++ side
CString member = "SomeString";
strcpy((char*)lParam, member.GetBuffer());
Then on C# side sb has not been changed
Any idea ?
Please if someone did it post the example,
I would greatly appreciate,
Roman

Hello,
1.
Is there a way of making a column in datagrid as a combobox.
So when the user wants to modifiy the fields in the datagrid, and
clicks in particular cell, the dropdown list will appear, and he can only choose the values from the list as a value for the cell.
2. How can you format row in datagrid, so that the row spans the whole
lenght of the datagrid, and does not stop in the middle, etc..
Thank you.

try

To do custom formatting use
DataGridTableStyle and DataGridTextBoxColumn etc.
http://www.syncfusion.com/FAQ/WindowsForms/Default.aspx#44
has bunch of information

Hi,
I was hoping someone might help me with a with a serialization problem. I am trying to serialize multiple objects to the same disk file. Below is the code I am using to save and restore an individual object, however I really need to save many objects to disk.
Any thoughts and help would be very much appreciated.
<br />
static void saveFile()<br />
{<br />
IFormatter formatter = new BinaryFormatter();<br />
Stream stream = new FileStream("2005.pp1", FileMode.Create, FileAccess.Write, FileShare.None);<br />
formatter.Serialize(stream, PPeriod);<br />
stream.Close();<br />
}<br />
static void restoreFile()<br />
{<br />
IFormatter formatter = new BinaryFormatter();<br />
Stream stream = new FileStream("2005.pp1", FileMode.Open, FileAccess.Read, FileShare.Read);<br />
PayPeriodSerial = (PayPeriods) formatter.Deserialize(stream);<br />
stream.Close();<br />
}<br />

Hi!
You can simply serialize more than one object to the same stream:
IFormatter formatter = new BinaryFormatter();<br />
Stream stream = new FileStream("2005.pp1", FileMode.Create, FileAccess.Write, FileShare.None);<br />
formatter.Serialize(stream, PPeriod1);<br />
formatter.Serialize(stream, PPeriod2);<br />
formatter.Serialize(stream, PPeriod3);<br />
stream.Close();
You'll get all the objects when deserializing in exactly the same way.

mav

Hi. I have a GUI-Service remoting relationship set up with 2 remotable objects (1 used for sending messages from the service to the GUI to be displayed and 1 for user requests to be sent from the GUI to the service). The remoting is working well...except that for I receive multiple calls on the receiving end of the remoting. As I debug, I only encounter my call one time, but on the receiving end, there will be 2 occurrences. I must have something set up not quite right here - has anyone experienced this or have any tips that may help?
Thank you,
Dusty

I figured it out. Had the eventhandler wired up twice - figured it must be something like that!
Have a great day!

I'm using a custom bi-directional TCP channel to do my remoting. Using this channel, the client can receive messages back from the server once the client connects to the server.
My problem is that over a WAN/Internet environment, my custom channel is getting disconnected for no apparent reason. I have 2 questions: should I expect unstable connections over WAN/Internet? And also, to re-establish a connection, is it better to reconnect to the server objects, or go into the disconnected channel and try to re-establish the socket connection?
If anyone can answer either of these questions, or point me in the right direction, I'd appreciate it.

Networks by their very nature can be disconnected. It is just like file permissions, memory allocation, and other limited resources. Any networked system should be designed in such a way that it will deal if one side can not contact the other.
Another thing to keep in mind is that with .Net Remoting, objects are kept alive by leases so it is not dependent on the client side to constantly make "pings". You may want to twiddle the settings found in the LifetimeServices class, especially the RenewOnCallTime . It may very well be the reason why the system is failing is because the server got rid of its representation of the object because it has exceed its lifetime. This should be an obvious exception though and only applicable to client activated objects.

Hi friends,
I have a doubt about a new feature, custom events in VB.NET. Do anybody know the exact equivalent in c#. If someone, please help me.

Yes. Create a delegate defining how your function will look like (or alternatively, use an existing delegate like System.EventHandler):
public delegate void MyDelegate(int number, string text);
Then define an event in your class:
public event MyDelegate MyEvent;
And to raise the event in your class:
if(MyEvent != null)
{
MyEvent(5, "hello!");
}
